%D Written at the end of 2007, this module is dedicated to Taco. Reaching this
%D point in \LUATEX\ was a non trivial effort. By visualizing a bit what happens
%D when pages come out of \LUATEX, you may get an idea what is involved. It took
%D much time an dedication to reach this point in the development. Add to that
%D those daily Skype intense discussion, testing and debugging moments. Time flies
%D but progress is impressive. The motto of this module could be: what you see
%D is what you get. An there is much more to come \unknown.
